Chiral perturbation theory of muonic hydrogen Lamb shift: polarizability contribution
Jose Manuel Alarcón, Vadim Lensky, Vladimir Pascalutsa
The proton polarizability effect in the muonic-hydrogen Lamb shift comes out as a prediction of baryon chiral perturbation theory at leading order and our calculation yields for it…
Proton polarizabilities: status, relevance, prospects
Vladimir Pascalutsa
This is a brief review of the status of understanding the proton polarizabilities in chiral perturbation theory and of their relevance to the `proton charge radius puzzle'.
Analytic structure of theory using light-by-light sum rules
V. Pauk, V. Pascalutsa, M. Vanderhaeghen
We apply a sum rule for the forward light-by-light scattering process within the context of the quantum field theory. As a consequence of the sum rule a stringent causality c…
Separation of proton polarizabilities with the beam asymmetry of Compton scattering
Nadiia Krupina, Vladimir Pascalutsa
We propose to determine the magnetic dipole polarizability of the proton directly from the beam asymmetry of low-energy Compton scattering based on the fact that the leading non-Bo…
Pion-mass dispersion relation in the baryon sector
Vladimir Pascalutsa, Marc Vanderhaeghen, Jonathan M. M. Hall +1
By looking at the complex plane of the pion-mass squared we establish a dispersion relation which the static quantities, such as baryon masses, magnetic moments, polarizabilities,…
